This confirms nothing. He stopped short of calling it obstruction of justice. The prosecution can move forward but how can they make a case when the literal investigators can't pin an actual crime. This was a good day for Trump judging by what I've read.
Seriously, I heard a long excerpt read on MSNBC and even they say this supports the Presidents claim that he did not try to end the wider Russia probe.
I don't think there has been much evidence of this to begin with, the dangerous parts for the President have involved his handling of the Flynn case.
